Ion Percentages Actual Percentages are listed in the Mass Calibration table, outlined in red. The range
of acceptable values is presented in the 4 adjacent columns, outlined in blue in the
figure below.
Example: The percentage of mass 50, first row, should fall within 0.5 to 2.5%, and
must fall within 0.4 to 3.0%, for the mass spec to be properly calibrated.
Boxes shaded with red, like those shown in the figure above, indicate that the actual
percentage is outside that range for that fragment (row). For example, in the third row
of the table above for mass 69, the actual percentage is 6.37 when it should fall above
8.00. Here, mass 69 requires adjustment of the Resolution and/or Ion Energy to
correct the Actual Percentage.
Status Column The Status Column provides categorical view of the actual percentages. The values
OK, OK Low, OK High, Low or High indicate whether the actual percentage for that
ion are within best range (OK) or outside (Low or High). Values of High or Low are not
acceptable. Adjust the corresponding mass fragments.
